-Be it known that I, THOMAS Jnrrnnsor:

' BnUMnAoK, a citizen of the United States,

a to each other.

,Improvements in Buildin and a resident of Cape Girardeau, in the county of Cape Girardeau and State of Mi souri, have invented certain new and useful g lValls, of which the following is a'specification.

li l'y invention relates to building walls floors androofs, and the purpose of my invention is the provisionof a building wall. composed of a plurality of. building units each ofwhich is provided with tongues and grooves deslgnedto receive the plaster ma terial and to thus firmly secure the materialto the units and to thereby secure the units It is also a purpose of my invention to provide a wall; floor or roof construction in whichthe building units above referred to are employed as laths sheathing or studding,

: in such manner that the plastic material used in forming. any of these constructions is made to firmly secure one element to another and to be reinforced by the units.

Another purpose of my invention is the provision of a building. walle mbodying my building units in boththe inner and outer walls of abuilding in conjunction with a concrete wall arranged between the two but contacting only with the outer wall so as to provide a dead air space for preventing the transmission of moisture through the building wall. I

I will describe one form of building unit and one form of building wall, each embodying my invention, and will then point out the novel features thereof in claims.

In the accompanying drawings:

Figure '1 is a view showing in perspective one form of building unit embodying my invention.

Figure 2 is a perspective View of a portion of a building wall embodying my invention and in which a plurality of building units shown in Figure 1 are employed.

Figure 3 is a vertical sectional view.

' Figure-3t is a transverse sectional view.

-Similar reference characters refer to'similar parts in each of. the several views.

. Referring specifically to the drawings and particularly to Figure 1 A designatesa building unit embodying my invention which is formed of a singlelength of wood orother suitable material ,of rectangular formation, and is provided on each of its dovetailed channels I 18.

BUILDING WALL.

1920. Serial No. 373,314.

longitudinal edges witha pair of tongues i-Sand 15 and an intermediate tongue 16 between the two all oi such tongues being coextensive in length with the unit. The tongues i5 and 15 are tapered transversely from their point of connection with the unit to their outer edge, while the tongue 16 is formed with right angularly disposed faces. .ltwill thus be seen that because of the contour of the tongues 15, 15 and 16, longitudinally extending grooves 17ers formed which are substantially "t shaped in cross section, with the grooves at one side of the tongue 16 arranged in convergent relation with respect to the other groove. The outer edge of the tongue 16 is disposed beyond the outer edges of the tongues 15 and 15 for a purpose which will be hereinafter described.

From the construction of the building unit just described, it will be clear that when one unit is associated with a unit of like construction as shown in Figures 2 and 3, the tongues 16 on the confronting edges of any two units will contact with each other and thus maintain the edgesv of the. confronting tongues 15 and 15 in spaced relation to each other so as to provide a dovetailed-channel 18 between each pair of tongues. Thus, a

pair of dove-tailed channels 18 is provided at the confronting edges of each pair of units with the grooves of each pair disposed upon opposite sides of the tongue 16.

Referring now to Figures 2, 3 and 4 I have here shown a building wall'comprising an inner wall Fland an outer wall TV. The inner wall comprises a plurality of laths L which are constructed in accordance with the building unit shown in Figure 1 and are arranged one upon'the other to'provide the The laths L are nailed or otherwise secured to studs 5 arranged at intervals between the walls W and VJ in the 1113111161 shown in Figure 2. As

each stud S is also constructed in accordance with the building unit shown in Figure The remainder of the inner wall W is made up of layers of plaster P and P applied to the opposite sides of the laths L. in the application of the plaster to the laths, portions of the former repose within the'jdove-tailed channels 18 so that when the plaster becomes hardened, each layer ofplaster will be formed on its inner with dove-tailed tongues 19 that terlocl: with the tongues 19 to firmly secure the layers of plaster upon the laths, while the plaster tongues 19 serve to reinforce the several laths thus providing a wall of strong and durable construction.

The outer wall W is also comprised of a plurality of laths, designated at L, arranged in superimposed relation in the same manner the. lathe comprising the inner wall. The inner side of the laths L are coated with a relatively thick layer of concrete designated at C, this layer being of such a width as to occupy approximately one half. of the distance between the walls N and iv in order to provide a dead air space between the two. In the application of the concrete wall C to the lathe L it will 1' beclear that portions of concrete will repose within the dove-tailed channels 18 of the laths to provide tongues in a manner similar to the tongues 19 of the layers oiplaster P and P." Similarly, these tongues serve to reinforce the laths, while the tongues 15 and 15 of the laths serve to reinforce the concrete, this mutual reinforcement providing a wall oi great strength. 'The dead air space between the two walls prevents the transmission of moisture from the outer wall to the inner wall so that the latter is maintained dry at all times. The outer surface of the laths L may be covered with any'suitable form of plastic material such as stucco, designated at T. This layer of plaster has portions thereof reposing within the-dovetailed laths L". thereby serving as an additional reinforcement for the lathe Li and the latter in turn securely retaining the plastic material thereupon.

As illustrated to advantage in Figure 4, the grooves 17 and 1? of the stul S are so arranged as to receive portions of the plustic material comprising the layers P and C .so that when these materials become hardened they reinforce the studs, while the tongues of the latter provide an addltlonal reinforcing means :tor the layers of plastic material.

or flooring in the construction of roots and floors. It will be further manifest that I have provided a building wall of strong and durable construction in which all of the parts comprised in the wall coact to muituallyreinforce each other, the dead air space provided between the walls preventing It is to be understood that through the wall wherein it is used to agreater extent than where no such-lathing is used. v

r-rlthough I have herein-shown and described only one form ofbuilding unit and one torin of building wall, eachembodying my'invention, it is tobe understood that various changes and rnodifications may be made herein without departing from the spirit oi" the invention and the spirit and scope of the appended claims.
